Environment

ITMS 8.x

Cause

The "Agent Registration Policy - Allow" was disabled.

The Agent logs indicated that "Agent registration status is set to 'Pending'", which means it is waiting for approval to be registered based on the rules assigned under the "Agent Registration Policy - Allow" policy.

Resolution

Enable the "Agent Registration Policy - Allow" policy:

• Go to the SMP Console, under Settings>Agents/Plug-ins>Symantec Management Agent>Registration Policies
• Make sure the "Agent Registration Policy - Allow" policy is turned on and has the proper rule to allow those new machines.
